HTML-2-CSS Mapping

Checks that browsers implement properly the html2css stylesheet (rules about borders, disabling border-collapse for clarity)

1: The border of the table element should be 0px hidden gray:

border-width:0px is the initial value;
border-style:hidden comes from table:matches(..., [rules=groups], ...);
border-color:gray comes from table

<table border="0" rules="groups"><tbody><tr><td></td></tr></tbody></table>

2: The border of the table element should be 1px outset black:

border-width:1px comes from table[frame=box] (1/2);
border-style:outset comes from table[frame=box] (2/2);
border-color:black comes from table:matches(..., [rules=groups], ...)

<table border="0" rules="groups" frame="box"><tbody><tr><td></td></tr></tbody></table>

3a: The border of the table element should be 10px outset gray:

border-width:10px comes from table[border=$w];
border-style:outset comes from table[frame=box] (2/2);
border-color:gray comes from table[border=$w]

3b: The border-top of the td element should be 1px inset gray:

border-width:1px comes from table[border=$w] > ...td;
border-style:inset comes from table[border=$w] > ...td;
border-color:gray comes from table[border=$w] > ...td

3c: The border-left of the td element should be 1px hidden gray:

border-width:1px comes from table[border=$w] > ...td;
border-style:inset comes from table[border=$w] > ...td;
border-color:gray comes from table[border=$w] > ...td

<table border="10" rules="groups" frame="box"><tbody><tr><td></td></tr></tbody></table>

4a: The border of the table element should be 1px outset gray:

border-width:10px comes from table[border=$w];
border-style:outset comes from table[border=$w];
border-color:gray comes from table[border=$w]

4b: The top border of the td element should be 1px solid gray:

border-width:1px comes from table[rules=all] > ... td;
border-style:solid comes from table[rules=all] > ... td;
border-color:gray comes from table[rules=all] > ... td

<table border="yes" rules="all"><tbody><tr><td></td></tr></tbody></table>

5a: The left border of the table element should be ? hidden ?:

border-style:hidden comes from table[frame=hsides];

5b: The right border of the table element should be 10px solid gray:

border-width:10px comes from table[border=$w];
border-style:solid comes from [style];
border-color:gray comes from table[border=$w]

<table border="10" frame="hsides" style="border-right-style: solid"><tbody><tr><td></td></tr></tbody></table>
